Sura al-Nūr 24:39

وَٱلَّذِينَ كَفَرُوٓا۟ أَعْمَٰلُهُمْ كَسَرَابٍۭ بِقِيعَةٍ يَحْسَبُهُ ٱلظَّمْـَٔانُ مَآءً حَتَّىٰٓ إِذَا جَآءَهُۥ لَمْ يَجِدْهُ شَيْـًٔا وَوَجَدَ ٱللَّـهَ عِندَهُۥ فَوَفَّىٰهُ حِسَابَهُۥ وَٱللَّـهُ سَرِيعُ ٱلْحِسَابِ

wa-lladhīna kafarū aʿmāluhum kasarābin biqīʿatin yaḥsabuhu l-ẓamānu māʾan ḥatta idhā jāʾahu lam yajidhu shayʾan wa-wajada allāha ʿindahu fa-waffāhu ḥisābahu wallāhu sarīʿu l-ḥisābi

But the Unbelievers,- their deeds are like a mirage in sandy deserts, which the man parched with thirst mistakes for water; until when he comes up to it, he finds it to be nothing: But he finds Allah (ever) with him, and Allah will pay him his account: and Allah is swift in taking account.
